All of the fiber optic borescopes I’ve looked at are in the $300 range, add a camera to that and your looking at a grand. That seems like an expensive way to look inside the crankcase, unless of course you happen to have one in your tool box. . . . . DG
I am not not suggesting buying one of these
inspection cameras from Harbor Freight but the $89 one looks interesting. It looks like it uses LEDs instead of fiber-optics for illumination.
